（1）效果
如上图所示的效果，这里我们使用vue 制作。
(2)使用技术 vue + vue-baberrage
1.安装：
npm install vue-baberrage
2.引入
方式一：
import Vue from 'vue'
import { vueBaberrage } from 'vue-baberrage'
Vue.use(vueBaberrage)
方式二：
const vueBaberrage = request('vue-baberrage').vueBaberrage
方式三：
<script src="./dist/vue-baberrage.js"></script>
3.使用
HTML
<div id="app"> <vue-baberrage :isShow= "barrageIsShow" :barrageList = "barrageList" :loop = "barrageLoop" > </vue-baberrage> </div>
JS
import { MESSAGE_TYPE } from 'vue-baberrage'
export default {
name: 'app',
data () {
return {
msg: 'Hello vue-baberrage',
barrageIsShow: true,
currentId : 0,
barrageLoop: false,
barrageList: []
}
},
methods:{
addToList (){
this.barrageList.push({
id: ++this.currentId,
avatar: "./static/avatar.jpg",
msg: this.msg,
time: 5,
type: MESSAGE_TYPE.NORMAL,
});
...
(3)实例演示
这个封装成一个 vue的组件：
<template>
<div class="barrages-drop">
<vue-baberrage
:isShow="barrageIsShow"
:barrageList="barrageList"
:maxWordCount="maxWordCount"
:throttleGap="throttleGap"
:loop="barrageLoop"
:boxHeight="boxHeight"
:messageHeight="messageHeight"
>
</vue-baberrage>
</div>
</template>
<script>
import Vue from 'vue';
import { vueBaberrage, MESSAGE_TYPE } from 'vue-baberrage';
Vue.use(vueBaberrage);
export default {
name: 'Barrages',
data() {
return {
msg: '马优晨就是个辣鸡~',
barrageIsShow: true,
messageHeight: 3,
boxHeight: 150,
barrageLoop: true,
maxWordCount: 3,
throttleGap: 5000,
barrageList: []
};
},
mounted() {
this.addToList();
},
methods: {
addToList() {
let list = [
